8. Instant heat function
In situations where there is insufficient hot water in the tank, users may press the ‘Instant’ button to
generate hot water quickly. This mode activates the heating elements and the heating indicator will
flash 3 times upon activation. If the heat pump is running on ‘efficiency’ mode, it will switch to ‘hybrid
turbo’ mode when running on instant mode.
When the desired temperature is reached, the heating light will go off and the water heater will resume
normal operation. Otherwise, users may cancel this heating function by pressing ‘Instant’ again. The
heating indicator will flash once and go off to indicate the operation is cancelled.
6. Heating modes
There are two heating modes in the system. Upon making a mode selection, the system will take 3
minutes to reprogram to your selection.
Efficiency mode: energy efficient heat pump heating
Hybrid turbo mode: heat pump and speed (element) heating
7. MAX and AES
Toggle the AES/
►►
button to activate either the MAX/
►►
mode, AES mode, or both. AES mode will not
run simultaneously with timers and will take precedence over them.
MAX is an A. O. Smith technology that allows users to get consistent hot water for long periods of
time. You can turn it on to cater for an unexpected surge in demand for hot water.
AES is a memory chip that records up to 21 days of your family’s usage habits. It preheats water
according to your family’s needs and sends the heater into energy saving mode at required intervals,
saving energy by minimizing thermal loss.
9. Hot water display
The heater can display the amount of hot water available. The five light blocks on the left of the panel
are an indication of the quantity of hot water in the tank.
Red – hot
Orange – warm
Green - cool
10. System reset
Press and hold the ‘program’ and ‘instant’ buttons for 8 seconds to revert to factory state. When the
system is reset, all screen indicators will glow for 2 seconds and the system will go offline.
